A magnet levitates over a rapidly spinning aluminum disc. As a control experiment, a brass nut may be used to demonstrate that the levitation is an eddy current effect. The disc spins at several ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Unlike mechanical brakes, which are based on friction and kinetic energy, eddy current brakes rely on electromagnetism to stop objects from moving. Eddy currents are created when a conductor passes ...
